In this paper are shown the results of the production characteristics of the perennial ryegrass (Lolium perenne L.) cv. ‘Naki’, which grown in rows with different row spacing and seed rate in the agroecological conditions of central Serbia in three successive analysed years. Four levels of two observed factors were used in the experiment: row spacing (12.5; 25; 37.5 and 50 cm) and seed rate (9, 16, 23 and 30 kg ha-1). Due to the analyses, the height of the tiller, the length of the spike and the number of spikelets per spike gave better results by sowing in wider rows (37.5 and 50 cm) using lower seed rate (9 and 16 kg ha-1). Seed yield and harvest index responded favourably to sowing in rows at a wider row spacing (37.5 and 50 cm) in combination with a lower seed rate (9 and 16 kg ha-1), while shoot dry weight gave better results by sowing in narrower rows (12.5 cm) with lower seed rate (9 and 16 kg ha-1). Using the appropriate row spacing in sowing and the optimum of seed rate provides the highest results of the production characteristics of the perennial ryegrass that can be applied to further production.
This chapter analyzes plant production from the perspective of development rural areas and it is based on the case study for rural areas on territory of Smederevo. The main goal of this chapter points to the current situation in plant production as one of the most important agricultural activities and that creates the basis for future development. It will be presented data collected from Census of agriculture, yearbooks, and local reports, but also data collected in the field. The authors apply theoretical and practical frame of research based on the case of study, which is oriented on used agricultural land, realized production and yield in period 2013-2017.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
